Mantain Property

[Mike]

Hi,
I don't know how to mantain the value of a Property of my WebCustomControl.
I've my Control and set:
------Code in Page container of contrl ----...
....
if(!IsPostBack)
myControl.DataSource = myDataSource;
myControl.DataTextField = "TextField";
myControl.DataValueField = "ValueField";
.....

------ Code in Contrl -----
.....
public string DataTextField
{
get{return this._dataTextField;}
set{_dataTextField = value;}
}
....

and when PostBack raised the value of this propertys are null
I can mantain the value using Session, but is little elegante.

Someone has an example about this?

THANKS!

To maintain data in a custom control across postbacks, don't store the data
in a field. Instead store it in ViewState.

public string DataTextField
{
get{
if (ViewState["DataTextField"] == null) return "";
return ViewState["DataTextField"] as string;
}
set{
ViewState["DataTextField"] = value;
}
}
